Windows App SDK vs. .NET

The Windows Software Development Kit (SDK) contains headers, libraries, and tools you can use when you create apps that run on Windows operating systems. With the Windows SDK, you can begin building Universal Windows apps and desktop apps for Windows 10, Version 1511. This SDK also supports building Windows apps and desktop applications for Windows 8.1, Windows 8, Windows 7, Windows Vista, Windows Server 2012, Windows Server 2008 R2, and Windows Server 2008.

.NET is a free, open-source, cross-platform framework developed by Microsoft for building modern applications and powerful cloud services. It supports multiple operating systems, including Windows, Linux, and macOS, enabling developers to create a wide range of applications, from web and mobile to desktop and cloud-based solutions. With a unified platform, .NET allows for the use of a single codebase across various application types, enhancing productivity and reducing development time.
